visit the Asus website, find your mobo and check cpu support.
I think it depends on pcb version / revision, and the bios version. The former is usually printed somewhere on the board itself; there's nothing you can do about it. The latter can be flashed to a newer version if you know what you're doing. Easiest if you can boot it using an older supported cpu (borrowed)then update the bios directly from the Asus site, then put in your shiny new E8400. Maybe a local pc shop could do this for you if they have a spare conroe cpu lying about??
failing that I have read it is possible to obtain the correct bios using another pc, save it to a usb flash drive and somehow boot with it attached(??).
I have sent it back to Overclockers to have the new bios installed.They couldn't guarantee a replacement would have the new bios,and the Asus website response is sslloooowww, long way round but easy and safe. John
